NOT ENOUGH SPACE ON DISK FOR STORE
Error Number
44
The store operation will overflow the available disk space. Insert a new disk or
purge files to create free disk space.
OVERLOAD ON INPUT A, POWER REDUCED
Error Number
58
You have exceeded approximately +14 dBm at one of the test ports. The RF
output power is automatically reduced to −85 dBm. The annotation P⇓ appears
in the left margin of the display to indicate that the power trip function has been
activated. When this occurs, reset the power to a lower level, then toggle the
softkey to switch on the power again.
OVERLOAD ON INPUT B, POWER REDUCED
Error Number
59
You have exceeded approximately +14 dBm at one of the test ports. The RF
output power is automatically reduced to −85 dBm. The annotation P⇓ appears
in the left margin of the display to indicate that the power trip function has been
activated. When this occurs, reset the power to a lower level, then toggle the

PHASE LOCK CAL FAILED
Error Number
4
An internal phase lock calibration routine is automatically executed at
power-on, preset, and any time a loss of phase lock is detected. This message
indicates that phase lock calibration was initiated and the first IF detected, but
a problem prevented the calibration from completing successfully. Perform the
“Source Pretune Correction Constants (Test 43)” on page 3-6. This message may
appear if you connect a mixer between the RF output and R input before turning
on frequency offset mode. Ignore it: it will go away when you turn on frequency
offset. This message may also appear if you turn on frequency offset mode before
you define the offset.
PHASE LOCK FAILURE
Error Number
7
The first IF signal was detected at pretune, but phase lock could not be acquired.
Refer to Chapter 7 , “Source Troubleshooting.”
